Roofing situations are diverse and each demands a unique approach. Some substrates have unique properties that make them require primers for optimal adhesion. Metal roofs can be an example of such a situation. Given their susceptibility to oxidation, a specialized primer may be necessary to protect the metal and provide a sturdy base for the roof coating to adhere.

The process of roofing substrate priming is a crucial step when working with porous or uneven surfaces. By filling in gaps and smoothening out inconsistencies on the substrate, the primer promotes a more uniform and receptive surface for the roof coating. Therefore, substrates such as concrete or weathered bitumen may greatly benefit from priming before coating.

Utilizing Manufacturer’s Guidelines for Primer Use

When in doubt, always refer to the manufacturer’s guidelines. These resources are valuable in determining the necessity of a primer for specific roofing substrate and coating types.
